Effects of Grape Seed Extract on Pancreas Weight in Diabetic Rats

GÜLBAHÇE MUTLU, Elif | ARSLAN, Emine | ARIKOĞLU, Hilal

Introduction: Pancreas is a vital organ that produces metabolic hormones and enzymes. Any change in the function of this organ can directly affect the physiological mechanism in the body. Type II diabetes mellitus is a complex metabolic disease. And, this is emerged from either a failure in insulin secretion from pancreatic beta-cell cells or a decrease in pancreatic beta-cell mass. Despite the use of synthetic drugs in the treatment of metabolic diseases, many traditional plant therapies in the world are still used in the treatment of these diseases. The possible effects of grape seed extract ...Daha fazlası

Detection of the Electronic Attributes of the Nanostructured Materials with Fuzzy Logic

ALLAHVERDİ, Novruz | GENCER, Muhammet Çağrı | VARDAR, Necati

This is a study, in which a trial was done to estimate the energy band gap (Eg) of single-walled carbon nanotubes (SWCNTs) by using a fuzzy logic algorithm that uses five inputs (strain value, fermi energy level, average energy, repulsive potential and electronic band structure energy).

Energy Supply Chain and Energy Security

ÖZKAN NESİMİOĞLU, Şerife

Energy Supply Chain and Energy Security Şerife Özkan Nesimioğlu Correspondence: serife.ozkan.nesimioglu@karatay.edu.tr In general, supply chain security is a prominent part of energy security, which is defined as “uninterrupted availability of energy sources at an affordable price” by International Energy Agency (IEA). In more detail, energy security can be separated into two sub-definitions as short and long- term energy security. Short term energy security focuses on the ability of the energy system to react promptly to sudden changes in the supply- demand balance. Here, sudden changes refer ...Daha fazlası

Interval Type-2 Fuzzy Analytic Hierarchy Process Application on Warehouse Performance Measurement Criteria Defined

YAŞAR, Esra | ARAS, Nil

Warehouse performance measurement is of great importance for the development of companies. The companies are to measure their current situation in order to attain ability relating to realizing the improvement process. In this measurement phase, they have to decide what is considered and what proportion it is done. In this study, the most effective factors were determined using the interval type-2 fuzzy analytic hierarchy process method for the factor values that are effective in warehouse performance measurement. The reason to use this solution method is that because of having 3 dimensional me ...Daha fazlası

İnsan Kuru Kafataslarında Foramen Ovale ve Foramen Spinosum'un Morfometrik Olarak İncelenmesi ve Olası Varyasyonlar

AYDIN KABAKÇI, Anıl Didem | AKIN, Duygu | ALPA, Şerife | DURSUN, Fatma Nur | YILMAZ, Mehmet Tuğrul

Özet Foramen ovale ve foramen spinosum, os sphenoidale’nin ala major’unun facies infratemporalis’i üzerinde yer alan önemli anatomik deliklerdir. Deliklerin yapısal farklılıkları ve ebatları, içerisinden geçen vasküler yapılar ile uyumuna bağlıdır. Örneğin; arteria meningea media’nın (a. meningea media) erken divizyonu sonucunda ön ve arka köklerin şekillenmesi foramen spinosum duplikasyonu ile sonuçlanabilmektedir. Foramen ovale, özellikle skuamöz hücreli karsinom menenjiom’un bilgisayarlı tomografi (CT) eşliğinde teşhisi amacıyla kullanılmaktadır. Trigmeninal nevralji, tek ya da çift taraflı ...Daha fazlası

The effects of degassing, grain refinement & Sr-addition on melt quality-hot tear sensitivity relationships in cast A380 aluminum alloy

ULUDAĞ, Muhammet | ÇETİN, Remzi | DIŞPINAR, Derya | TİRYAKİOĞLU, Murat

Hot tearing tendency of A380 with various element additions (Sr, Sr+Ti, Ti, B and B+Sr) was investigated. Constrained rod casting (CRC) hot tearing test method was used to characterize the hot tearing sensitivity. Reduced pressure test (RPT) samples were produced from each condition and all trials were repeated three times. Number density of pores on the cross section of RPT samples was calculated via digital image processing and statistical analysis was carried out. Microstructure analysis was carried out to observe the effect of alloying elements. Hot torn cross sections were subjected to SE ...Daha fazlası

Neuroprotective Effects Of High-Dose Human Albumin Against Traumatic Spinal Cord İnjury in Rats

YILDIRIM, Timur | OKUTAN, Özerk | AKPINAR, Elif | YILMAZ, Ali | IŞIK, Hasan Serdar

BACKGROUND AND OBJECTIVES: Human serum albumin (HA) is a unique multifunctional protein with neuroprotective properties. We aimed to delineate the mechanisms of HA-induced neuroprotection, supresses inflammatory response and lipid peroxidation after spinal cord injury (SCI). METHODS AND STUDY DESIGN: Adult female Wistar rats weighing 210-250 g were used for the study. The rats were randomly and blindly allocated into five groups. The one-way analysis of variance (ANOVA) for parametric data and Shapiro-Wilk test was used for evaluating the normal distribution of the variables. Kruskal-Wallis fo ...Daha fazlası

Is Hypnosis Innocent? Physiopathological Evaluation of Effect on Vital Findings

SUNAR, Füsun | KÜÇÇÜKTÜRK, Serkan

Aim: Hypnosis is used in Complementary Medical Treatments. Our aim is to assess whether hypnosis is a side effect by evaluating effect in vital signs. Vital signs change in pathologic conditions. Fever, pulse, blood pressure and number of breaths is a good indicator of side effect evaluation. Methods: Healtly Twelve volunteers, six women and six men aged between 18 - 65 years who had received the necessary permits and consent. The hypnosis room was quiet and at room temperature to minimize the effect of vital signs. Participants used rapid hypnosis technique. Measurements were made under the h ...Daha fazlası

Synthesis and characterization of a new poly (dithieno (3, 2-b: 2′, 3′-d) pyrrole) derivative conjugated polymer: Its electrochromic and biosensing applications

AZAK, Hacer | YILDIZ, Hüseyin Bekir | ÇARBAŞ, Buket

Synthesis and electropolymerization of a new conjugated dithieno(3,2-b:20,30-d) pyrole (DTP) derivative, namely, 2-(2-(2-(4H-dithieno[3,2-b:20,30-d]pyrrol-4-yl)ethoxy)ethoxy)ethanamine, (DTP-alkoxy-NH2) monomer are presented. The electrochemical, spectroelectrochemical effects and biosensor capability towards to glucose oxidase enzyme of P(DTP-alkoxy-NH2) polymer fi lm are investigated in detail during the placement of alkoxy-NH2 functional unit in the polymer. Electrochemical and optical results between neutral and oxidized states of the polymer fi lm show that (P(DTP-alkoxy-NH2)) has reversibl ...Daha fazlası

The effects of aflatoxin B1 on growth hormone regulated gene-1 and interaction between DNA and aflatoxin B1 in broiler chickens during hatching

GÜLBAHÇE MUTLU, Elif | ARSLAN, Emine | ÖZNURLU, Yasemin | ÖZPARLAK, Haluk

Many types of aflatoxin cause problems for both public and animal health. Aflatoxin B1 (AFB1) is the most toxic and commonly encountered fungal toxin that appears in poultry feed and in feeds stored under unsuitable conditions. AFB1 decreases feed quality, egg production and fertility of hatching eggs. Also, AFB1 alters the development of embryos by infecting eggs. We investigated using sequence analysis the changes caused by different concentrations of AFB1 on the promoter sequences of the growth hormone regulated gene-1 (GHRG-1) in chick embryo at 13, 17, 19 and 21 days incubation. DNA isola ...Daha fazlası

DURAN, Tuğce | KOÇAK, Nadir | AYDIN, Cihan | KAPLAN, Oktay İsmail | ZAINALBDEN, Hasanain Akram | CORA, Tülin

Malignant melanoma is a neoplasm of melanocytes or of the cells that develop from melanocytes. Although melanoma was once considered an uncommon disease, the annual incidence has increased dramatically over the past few decades, as have deaths from melanoma. The 3 Ras genes in humans (HRas, KRas, and NRas) are the most common oncogenes in human cancer; mutations that permanently activate Ras are found in 20% to 25% of all human tumors and up to 90% in certain types of cancer NRAS mutations in codons 12, 13, and 61 arise in 15–20 % of all melanomas. These alterations have been associated with a ...Daha fazlası
